Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a support structure for an air rectifier installed in equipment that requires the formation of an air curtain, such as an open storage case for refrigeration or refrigeration.

As an example of this type of structure, FIG. 2 shows a structure in which the blow-off section forming a cold air curtain covering the front opening of the open-air freezer/refrigerator case shown in FIG. 1 is constructed with a honeycomb-shaped rectifier.

First, referring to Fig. 1, the freezer/refrigerated open case 1 will be briefly explained. An inner box 3 is assembled at a predetermined interval within an outer box 2 made of a heat insulator and has a substantially U-shaped cross section. A cooling refrigerant evaporator 4 and a blower 5 are disposed in the holder to form a cold air ventilation path from the bottom to the ceiling through the back, and from a blow-off part 6 provided at the front end of the ceiling of this ventilation path. Circulating ventilation in which the blown out cold air is sucked in from the suction section 7 on the lower side allows the front opening of the case to be covered with a cold air curtain as shown by the arrow.

FIG. 2 shows the cross-sectional structure of the cold air blowing part 6, which includes a front support plate 8 provided longitudinally at the front end of the ceiling of the outer box 2, and a part of the ceiling of the inner box 3. An air outlet is formed between the rear support plate 9 formed with
A honeycomb-shaped rectifier 11 is installed by 0. The holding plate 10 is made by integrally molding a resin material or the like, and when attached to the outlet, the rear end side of the rectifier 11 is held between the flanges 101 on the front side, and the upper flange 102 on the rear side is bent and deformed. The clamping plate 10 and the rectifier 11 are integrated in such a manner that they are
is press-fitted into the air outlet, and the upper flange 102 is attached to the upper end of the rear support plate 9.
Therefore, a large amount of force is required for attachment, and even when the clamping plate 10 and the rectifier 11 are to be removed, it is very difficult to remove them due to the engagement of the upper flange 102.

Furthermore, in the support structure of the honeycomb rectifier 11 as described above, since the direction of the honeycomb mesh of the rectifier 11 cannot be changed, the rectifier 11
Since the blowing direction of cold air from the freezer is limited to one direction, changing the number of shelves arranged inside the freezer/refrigerating open shelf case and changing the angle of inclination of the shelves may be necessary. It has been difficult to always form a good cold air curtain at the front opening A of the front opening A. In particular, if the number of shelves is reduced and the distance between the top shelf and the rectifier 11 is large, the cold air curtain will be bent toward the inside of the refrigerator, so a good cold air curtain will not be formed in the front opening A. First, there was a defect in which outside air entered the warehouse.

In order to eliminate the above-mentioned defects, the present invention forms multiple holes in the upper and lower directions in the clamping plate that supports the honeycomb rectifier, and the protrusions of the spring plate attached to the rear support plate are inserted into the holes. By fitting, the direction of the honeycomb grains of the honeycomb-shaped rectifier can be changed, and a good cold air curtain is always created at the front opening of the freezer/refrigerator open case according to the status of the shelves arranged inside the refrigerator. The purpose is to form a

Examples of the present invention will be described below.

FIG. 3 shows an embodiment of the present invention with the same parts as in FIG.

The present invention is characterized by the clamping plate 20 and the rear support plate 9 which are adapted to clamp the rear end of the rectifier 11, and the other parts may be the same as the conventional ones. That is, holes 9 are formed in the rear support plate 9.
1 is provided, and a spring plate 12 is provided on the rear side.
is provided so that the protrusion 121 of the spring plate 12 protrudes from the hole 91. This spring plate 12 is an elastic plate material, and the opposite end 1 of the protrusion 121
22 to the rear side with your fingers etc., the protrusion 12
1 comes out from the hole 91 toward the rear side.

FIG. 4 is a view of the spring plate 12 portion of FIG. 3 viewed from the rear side, and the L-shaped portion at the lower end of the spring plate 12 is attached to the upper part of the rear support plate 9 by welding or the like.

On the other hand, the clamping plate 20 has flanges 201, 201 for sandwiching the rear end of the rectifier 11 on the front side, and a flange 202 for positioning the clamping plate 20 on the rear side. A hole 203 is formed into which the projection 121 protruding from the hole 91 can be inserted at the position where the clamping plate 20 is locked, and the hole 203 is arranged in multiple rows in the upward and downward directions as shown in FIG.
l ₁ , l ₂ , and l ₃ so that the rear end of the rectifier 11 can move upward and downward within the cold air blowing section 6.

A method of attaching and detaching the rectifier 11 using the clamping plate 20 and a method of changing the cold air blowing direction of the rectifier 11 will be described with reference to FIGS. 6 and 7, respectively.

Generally, the rectifier 11 is often made of resin and is relatively easy to compress in the direction perpendicular to the radial direction, and is installed by press-fitting so that it is slightly larger than the size of the outlet when it is sandwiched between the clamping plates 20. I try to do that.

When installing, please refer to Figure 6 and install the rectifier 11.
As the clamping plate 20 with the clamping plate 20 is pushed into the air outlet, the protrusion 121 is pushed into the hole 91 by the clamping plate 20, and the uppermost hole 2 formed in the clamping plate 20 is pushed into the hole 91.
When the projection 121 reaches the position 03, the projection 121 fits into the hole 203 due to its spring properties and becomes set. That is, the rear end of the rectifier 11 is held between the holding plates 20, and the space between the front support plate 8 and the rear support plate 9 is tight.
Since the protrusion 121 fits into the hole 203 and is locked so that it does not fall out, the set state shown in FIG. 3 is maintained even if a force is applied to push out the rectifier 11 due to its own weight or circulating air pressure.

Next, when removing the spring plate 12, refer to FIG. 7 and pull the end 122 of the spring plate 12 toward the rear with your fingers or the like or pull it upward, and the protrusion 121 will come out of the hole 203 and the lock on the clamping plate 20 will be released. The rectifier 11 and the clamping plate 20 can be easily removed.

In addition, the direction of cold air blowing out of the rectifier 11 is changed by the eighth
As shown in Figures a and b, in the same way as when removing the rectifier 11, pull the end 122 of the spring plate 12 toward the rear side with your fingers or the like or pull it upward to release the lock of the protrusion 121 from the clamping plate 20, and remove the clamping plate. Place the board 20 on top.
Move the spring plate 1 downward and when it reaches the specified position,
2, remove your finger from the end 122 of the protrusion 121
By fitting into the hole 203 and locking, the work of changing the cold air blowing direction is completed, and the cold air blowing direction can be changed from arrow _B1 to _B2 .

As mentioned above, when installing, just one touch,
When removing it, it can be attached and removed with a simple two-touch operation without requiring much force, and the cold air blowing direction can also be easily changed with just two touches.

Further, as shown in FIG.
By forming the rectifier 03a, the rectifier 11 can be easily mounted and moved.

As explained above, according to the present invention, it is possible to easily attach and detach the air rectifier with a simple structure, and the blowing direction of cold air can be easily changed, so that a good cold air curtain is always provided at the front opening. Can be formed. It should be noted that the present invention is not limited to the embodiments, and the shape of the spring plate 12 is arbitrary, and is not necessarily applied only to frozen/refrigerated open storage cases.
